What’s going on now in San Francisco is a 1950s R&B rebirth, led up by this 25-year-old, who fortifies his dead-on Bobby Darin-style lounge stuff with boisterous rock-out vocal bursts here and there, somewhat reminiscent of Little Richard but not quite that crazed. The timing couldn’t have been better, with Amy Winehouse gone, but you really need to know what you’re getting here: This isn’t simply homage but a depthlessly stubborn rebirth. All the songs are originals, the instruments are all vintage, and — get this — the recording itself was mastered straight to mono on the same L.A. studio lathe (a technology that preceded even analog tape) once used by such producers as Phil Spector. It sounds it, too, as vintage as you could ever ask for, including the songs (opener “Say I Wanna Know” is like a Spector vision of “Hit the Road Jack”). It’s one thing for guys like Jamie Liddell to recreate old sounds with digital futzing and quite another to run every component in sight through the Wayback Machine. A real treasure, this debut — I wish some of the neo-oldschool bop-jazz guys would go nuts like this. A+ —Eric W. Saeger
